18 Pin ZIF Socket

Specifications

• Pin Count: 18 Pins
• Package Compatibility: Standard Dual In-line Package (DIP)
• Pitch: 2.54mm (0.1") - Breadboard and standard perfboard compatible
• Row Spacing: Fits standard narrow (0.3") DIP ICs
• Contact Material: High-conductivity copper alloy
• Body Material: High-temperature plastic (UL94V-0 rated)
• Mechanism: Cam-actuated lever locking system
• Mounting Type: Through-hole (THT)

Applications

• Universal Programmers: Essential replacement or upgrade part for TL866II Plus, RT809F, and custom-built EEPROM/MCU programmers.
• Microcontroller Development: Ideal for rapidly testing code on 18-pin PIC microcontrollers (e.g., PIC16F628A, PIC16F84A) before soldering them into a final circuit.
• IC Testing Jigs: Build automated testing rigs for 18-pin logic gates, op-amps, or custom ASICs.
• Educational Kits: Perfect for classroom environments where students frequently handle and swap bare ICs.

Unlock New Capabilities

• If you've mastered: Flashing code onto development boards via USB.
• This component unlocks: The ability to move away from bulky dev boards. You can now easily program standalone 18-pin bare microcontrollers for deployment in final, miniaturized, custom PCB projects.
• Effort Level: Beginner. Simply solder the socket to your programmer or breadboard adapter, drop the chip in, and lock it.

Virtual Technician & Usage Guide

• ⚠️ Handling Warning: Always ensure the lever is completely in the upright (open) position before inserting or removing an IC. Forcing a chip into a partially closed socket will bend the component pins and permanently damage the internal contacts of the ZIF socket. Pin Orientation: Take care to align the notch on your IC with the corresponding notch or indicator on the ZIF socket to prevent reverse-polarity damage during programming.

Package Includes:

• 1 x 18 pin ZIF Socket

Frequently Asked Questions (FAQ)

• What does ZIF stand for?
  ZIF stands for Zero Insertion Force. It means no pressure is required to insert the IC when the socket is open.
• Will this fit a standard breadboard?
  Yes, the 2.54mm pitch pins are designed to fit standard breadboards, though the socket body may cover the center dividing trench.
• Can I use this for 16-pin or 14-pin ICs?
  Yes, you can use smaller DIP ICs in this 18-pin socket. Just ensure you align the chip correctly, usually by bottom-justifying it away from the locking lever.
• Is this socket meant for permanent installation?
  While it can be soldered permanently to a PCB, its primary use is for temporary connections during testing or programming.
• What IC packages are compatible with this socket?
  It is designed specifically for standard Through-Hole DIP (Dual In-line Package) ICs.
• Will this work with SMD/SMT chips?
  No, this socket is only for through-hole DIP components. You would need a specific SMD-to-DIP adapter for surface mount chips.
• How wide of a DIP chip can this accommodate?
  This specific 18-pin socket is designed for standard narrow DIP chips with a 0.3-inch (7.62mm) row spacing.
• Can the locking lever be replaced if broken?
  No, the lever and internal cam mechanism are a single assembled unit. If broken, the entire socket must be replaced.
• What happens if I insert a chip backwards?
  The socket itself won't be damaged, but if you apply power while the chip is backwards, you will likely destroy the IC. Always check the orientation notch.
• Does the socket add any resistance to the circuit?
  The contact resistance is extremely low (usually <50mΩ) and negligible for almost all digital and low-frequency analog applications.
• Can I use this for high-frequency RF circuits?
  It is not recommended. The internal contacts and physical size of the socket can introduce parasitic capacitance and inductance, which can interfere with high-frequency signals.
• How many insertion cycles is this rated for?
  High-quality ZIF sockets are typically rated for 10,000 to 25,000 actuation cycles under normal use.
• Why are the pins on the bottom so long?
  The pins are designed to be easily soldered into through-hole PCBs or inserted deep into breadboard contacts for a secure mechanical hold.
• Is it safe to wash a PCB with this socket attached?
  You should avoid getting flux remover or water inside the socket mechanism, as it can strip the factory lubrication from the cam lever or corrode the contacts.
